I have a network setup with 2 nodes that are setup for periodic IO sample and another node as the "hub" to receive the data. I am getting a lot of 8a:0C packets. I know that it is a modem Status of "Network when to sleep". Besides the obvious of the network when to sleep what causes this status? I can't find any other documentation. I will get 50 of those frames then one actual data frame. the network is set to sleep for 14 min and wake for 1 min. the nodes are 900 HP modules running 8067 firmware.
thanks for you help!!
